To all iii/20m may canoes m:

Be it known I, i l nciumsr JAMES OAKLEY a citizen of the United States resiiling at Col-penal, in the county of Cub peper ancl State or: Virginn have invented certain new and. useful Improvements in Wire-Clamps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in wire clamps and has relation more particularly to a device of this general character especially (lesignorl and adapted for use in connection wi l; a trolley wire, and it is an'object of the invention to provide a novel and improved clamp of this general character whi'eby the wire may be efl eclively supported from a hanger or the like.

Another object of the invention is to provide a novel and improved device of this general character embodying, a pair oi coactin clamping jawmcm'bers or cars together with novel and improved means whereby said clamping jaw members or cars are prevented from falling out.

in additional object of the invention is to i provide a device of this general character having novel and improved means whereby the clamping jaw members or cars are causml to tightly engage the wire with. which 'thc same is employed.-

lhc invention consists in the details of construction and in the combination and arrangement of the several parts of my improved clamp whereby certain important :ul vantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed. I.\

In order that my invention may be the better understood, 1 will now proceed to do scribe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view inclevation of a wire clamp constructed in accordance with an embodiment of my invention;

2 is a sectional View taken substantially on the line 2--2 of Fig. 1;

Fig. 3 a view in top plan of the structure as herein disclosed with the hanger stud engaging member removed; and

rig. 4 is a view in plan of the gilt ring as herein employed.

As disclosed in the accompanying drawings, 1 denotes a suspension member or nut provided at one end portion and at substantially the axial center thereof with the socket 2, or the like, adapted to receive a stud or hanger of a conventional type. The not 1 includes a shank portion 3 provided adjacent its outer or freee'nrl with an annular groove or channel 4. inwardly of said groove or channel 4:, the shank 3 is provided with the peripheral threads 5. i

The jaw members or ears 6 are of duplicate construction and are adapted to be tightly clamped or cng'agedwith the wire l V. Each of the jaw members 6 is provided' with an inwardly disposed lip or flange 7 substantially semicircular in form and which. engages within the groove 4. Each of the members 7 is also provided with a ledge 8 and anupstanding flange 9, said lip and flange also being substantially semicircular.

lO'denotes a nut engaged with the threaded portion which when screwed down upon the ledges 8 of tho jaw members 6 causes said jaw members to tightly clamp the wire \V. The end portion of the bore of the nut 10 opposed to the member 6 is enlarged to receive the flanges 9 whereby the jaws (5 are prevented from falling out.

I also find it of zulvantage to provide the shank 3 above the threaded portion 5 with a second annular groove or channel 11 in which is adapted to be tightly pinched or otherwise fitted a split ring 12, of soft iron, and which ring 12, when pplied, extends beyond the periphery of the shank 3 and serves to prevent the nut 10 from screwing up too far with respect to the jaw members 6 whereby further means are provided to prcvcnt said jaw members from falling or dropping out. The annular groovc or channel 4 in the shank 3 permits the jaw members or cars (5 to swivel or rotate around the shank 3' so that said jaw members or cars may be effectively with the wire W.

As is clearly illustrated in Fig. 2,tho.wall of the socket 2 of, the suspension member 1 is threaded so that the some may be effeosively engaged with a stud or hanger of the type now generally employed. It is also '30 be particularly noted; that the outer or v ga-1 adapted to engage said second in combination,

gagement with a hanger stud, an end por-' upper end of the member 1 is provided with an outstanding hexagonal head or the like-'1 particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason, I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. A clamp for a trolley wire comprising, in combinat1on,.a member adapted for en'- gagement with a hanger stud, two clamping members engaged with the member and eapable of rotation therearound, each of said clamping members being provided with an extern il ledge, and a tubular member threaded upon the first named member and the ledges of the clamping members to force one toward the other, named members oppose to the clamping members each being provided with a recess, said clamping members being provided with upstanding flanges extending within said recesses, the recess .of said second member constituting an enlargement of the bore 0 member. 2. A clamp fora trolley wire comprising,

a member adapted for ention of the member being provided with an annular channel, clamping members provided with inwardly directed ears seating within the channel of said first named memthreaded upon 1 the clampingmembers the faces of the second ber, each of said clamping members being )rovided with an external ledge, and a member threaded upon the first named member and engageable with the ledges of the clamping members to force said clamping members one toward the other.

3. A clamp for a trolley wire comprising, in combination, a member, adapted for en gagement with a hanger stud, an end portion of the member being provided with an annular channel, clamping members provided with inwardly directed ears seating within the channel of said first named mem ber, each of said clamping members being provided with an external ledge, a member threaded upon the first named member and engageable with the ledges of the clamping members to force said clamping members one toward the other, and means carri d by the first named member to limit the movement of the last named member in a direction away from the ledge.

4. A clamp for a trolley wire comprisin in combination, gagement with a hanger stud, an end portion of the member being provided with an annular channel, clamping members provided with inwardly directed ears seating within the channel of said first named member, each of said clamping members being provided with an external ledge, a member threaded upon the first named member and engageable with the ledges of the clamping members to force said clamping'members one toward the other, and means carried by the first namedmember to limit the movement of the last named member in a direction away from the ledge, said secondnamed member being provided with an annular recess, the clamping members being provided with flanges extending within said recess, said flanges being arranged within the recess at all times. v

In testimony whereof I hereunto affix my signature. WILLIAM JAMES CARL'EY.
